Description of Prepainted Rolled steel Coil for Construction Roofing
Prepainted Rolled steel Coil is a kind of coated steel coil/sheet. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. In its coating, Al accounts for about 55%, Si 1.6%, while the remaining is Zn. Aluminum zinc coils enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative.
Main Feature of Prepainted Rolled steel Coil for Construction Roofing
1.Corrosion resistance: It mainly depends on the aluminum protection. When the zinc being worn, the aluminum will form a dense layer of aluminum oxide, resist corrosion material to prevent further corrosion inside.
2. Heat resistance: Aluminum zinc alloy steel sheet has excellent heat resistance, can withstand high temperatures over 300 centigrade, and is similar with aluminized steel high temperature oxidation resistance. It often used in chimney pipes, ovens, fluorescent lighting device and the device cover.
3. Heat reflective: Galvanized steel plate heat-reflective high rate is twice as galvanized steel, often used to make insulation materials.
4. Economy: Because density of 55% AL-Zn is smaller than the density of Zn, so in the same weight and thickness of Galvanized zinc layer, aluminum-zinc steel plate is larger area more than 3% of galvanized steel sheet.
Applications of Prepainted Rolled steel Coil for Construction Roofing
1. Construction and building: roofing; ventilating duct; handrail; partition panel;etc.
2. Electric appliance: refrigerator; washing machine; refrigerator; DVD;etc.
3.Transportation: oil tank; road sign; etc.
4.Agriculture:barn; etc.
5.Others:vending machine; game machine; etc.

- Q: How are steel coils priced in the market?
- Steel coils are typically priced in the market based on various factors such as the current supply and demand dynamics, global steel prices, production costs, and market competition. Additionally, specific attributes of the steel coils, such as size, thickness, grade, and coating, can also influence the pricing. Overall, it is a complex process that involves analyzing multiple factors to determine the appropriate price for steel coils in the market.
- Q: What is the weight of a standard steel coil?
- The weight of a standard steel coil can vary depending on its size and thickness. However, a typical range for a standard steel coil is between 5,000 to 10,000 pounds (2,268 to 4,536 kilograms).
- Q: How are steel coils used in the oil and gas industry?
- Steel coils are used in the oil and gas industry for various purposes such as pipelines, storage tanks, and drilling equipment. These coils are commonly used to manufacture seamless and welded pipes that are essential for transporting oil and gas from production sites to refineries and end-users. Additionally, steel coils are utilized in the construction of storage tanks that store oil and gas in large quantities. They are also an integral part of drilling equipment, including offshore platforms, where they provide structural support and withstand high-pressure environments.
- Q: What are the different methods of coil blanking for irregular shapes?
- There are various methods of coil blanking for irregular shapes, including laser cutting, waterjet cutting, and die cutting. Laser cutting involves using a high-powered laser beam to cut through the coil material, providing precise and intricate cuts. Waterjet cutting uses a high-pressure stream of water mixed with abrasive material to cut through the coil, offering flexibility and accuracy. Die cutting utilizes a custom-made die to stamp out the desired shape from the coil material, ensuring uniformity and efficiency. Each method has its own advantages and suitability depending on the specific requirements of the irregular shape being blanked.
- Q: How are steel coils protected during storage and transportation?
- Steel coils are protected during storage and transportation through various measures. These include wrapping them with protective materials such as plastic or paper, using wooden or metal cradles to provide support and prevent damage, securing them with steel bands or straps to prevent movement, and storing them in well-ventilated and dry areas to prevent corrosion.
- Q: How are steel coils tested for strength and durability?
- Steel coils are typically tested for strength and durability through a series of rigorous procedures such as tension and compression tests, hardness tests, and impact tests. These tests help determine the coil's ability to withstand various loads and impacts, ensuring that it meets the required strength and durability standards. Additionally, other tests like fatigue tests and corrosion resistance tests may also be conducted to further assess the coil's performance and longevity.
- Q: I am doing a experiment on mild steel soaked in sodium chlorideanyone can enlighten me about the effect of the sodium chloride in engineering term ?The mild steel specimen which I soaked in the sodium chloride has orange rust on it
- The mild steel contains a lot of Iron. The NaCl solution quickly attacks the iron content and forms rust. Over time, the solution may also cause what is called 'Chloride Cracking' of the steel. Pitting corrosion of stainless steel due to chlorides would certainly produce a rust-colored product. Passivation can be used to maintain a good corrosion resistant surface of stainless steel process vessel. There are many commercial products for this purpose. In the pharmaceutical industry, this process is often called derouging, that is to remove the buildup of iron oxides on the stainless steel process surfaces
- Q: i know theres steel in it but what else?
- Chromium, nickel and molybdenum. Along with less carbon.
- Q: How do steel coils contribute to the construction machinery industry?
- The construction machinery industry relies heavily on steel coils, which are indispensable for the manufacturing of heavy-duty equipment. These coils play a pivotal role in the creation of structural components, such as beams, plates, and tubes, which form the framework of construction machinery. The exceptional strength and durability of steel make it the perfect material for these applications, as it can withstand immense loads and harsh working conditions.
